Analysis of an electromechanical generator implanted in a human total knee prosthesis

This paper describes a miniaturized electromechanical generator, integrable in a human total knee prosthesis, in which the mechanical energy, related to the knee joint movement, is converted into electrical energy. This device has been conceived in order to power an autonomous sensor system, integrated into the prosthesis, able to monitor the loads on the articular surfaces and to transmit those outside the body.
